Feeding livestock and poultry selection best pasture

In recent years, with the continuous development of animal husbandry and the implementation of the national policy of returning farmland to forests, forage grass planting industry has flourished, and raising grass and raising livestock has not only improved the structure of livestock and poultry rations, saved food, but also planted crops. Together, the aquaculture industry has improved the economic efficiency of the land. However, there are also some farmers who are blindly introducing some pasture varieties that have biological characteristics and growth habits that are contrary to the local environment and have different feeding habits. The result is that livestock and poultry do not love to eat, the production performance has not been improved, the grasses have not reached Purpose, economic efficiency is not high. Based on this, different forage species should be considered for different breeding stocks. 1, the kind of grass fed cattle can choose Mexican corn, alfalfa, Festuca mongolicus, Pennisetum, Sudan grass, etc., should not grow high-yield juicy leafy pasture. Mexican corn is suitable for growing in areas with an annual rainfall of more than 800 mm and a frost-free period of 180 days. When the plant height is 1.5 meters, it can be cut once a month. Forage dry matter contains 9.5% crude protein, 2.6% crude fat, and coarse Fiber 27.3%. The stems and leaves are crisp and juicy, sweet and palatable. They are also suitable for silage or modulation of hay. 2, the grass can be used to feed the sheep alfalfa, forage maize, wolfberry fruit, clover, winter grazing 70 ryegrass. In order to feed goats during the weedy season, the perennial leguminous alfalfa is preferred, and it is a semi-arid climate with strong drought resistance. It is suitable for goats in mountain areas. Alfalfa is known as the "king of pastures". It not only produces high grass yield, but also has excellent grass quality. It is rich in protein, vitamins and inorganic salts. Usually 4-5 kilograms of fresh grass can be used to produce 1 kilogram of hay, which is also suitable for making 苜蓿. Grass meal is made into pellet feed or full price material. It should be noted that sheep that are resistant to rough feeding should be fed with cornmeal and other coarse feeds with high crude fiber content. 3, planting grass to feed pig Ru Mex, swaying pine vanilla, polymer grass, grain wolfberry, bitter leeks, milk vetch, grass crickets, etc. are suitable for feeding pigs. Rumex and S. oleifera are both perennial herbaceous plants. They have strong adaptability to planting areas, deep rooted leaves, strong regenerative ability, no competition with grain and economic crops, high digestibility, suitable for swine, etc. animal. When the plants grow to 70-90 cm high, they are harvested and harvested 3-4 times a year. The whole leaves can be fed to the pigs, and they can also be cut into small sections of 2-3 cm, mixed with corn stalks at a ratio of 3:1. , to achieve the complementary advantages of nutrition, but no matter what kind of feeding method, the amount of feeding can not be too much to prevent affecting the intake of concentrate feed. 4, grass feeding rabbits can use chicory, ryegrass, bitter leeks, grass hibiscus, cricket king, Pennisetum, especially chicory is better. Chicory is a perennial herb of the Asteraceae family and is resistant to cold and heat. It does not require strict soil requirements. It can be used continuously for more than 10 years for a single planting, and its disease resistance is extremely strong. When the plant height is 50 centimeters, it is cut and cut once every 30 days. It can produce more than 150,000 kilograms of fresh grass per hectare. The palatability is excellent, and it can better satisfy the habits of rabbits to eat fresh grass, and can be used to plant grasshoppers and lotus root meal. For mixed feeding, the amount of pasture should account for 50% of total feeding. 5. Feeding gooses and gooses in a grass to feed roughage. Forages suitable for feeding include Russian forage dishes (concrete grasses), pine cone herb, seed grain millet, fescue, and chicory. Russian cuisine is a kind of perennial forage that has risen in recent years. It is hardy and cold, high in temperature, and does not choose soils. Farmland can be barren hills, idle plots, and riverside roadside can be planted, and can be interplanted with fruit trees and economic forests. Northern areas can be cut 4-5 times in spring, summer and autumn, and the south area can be cut 5-6 times per year. The output per hectare is 900-1500 tons. The output per 667 square meters can meet the needs of 130 gooses for 1 year. When fed, it can be properly matched with the above-mentioned other families of forages, and it can be better formulated as a mixed feed. 6, feeding grasses regardless of laying chickens, broilers, because of its physiological characteristics, should not eat large amounts of pasture. However, small-scale chicken farmers in the summer and autumn season, the amount of appropriate use of some stems and leaves grass species such as chicory, bitter leeks, Russian and even Chinese cabbage, sweet potato leaves, etc., chopped chicken, promote balanced nutrition.
